may first act as awls, as in the previously men
tioned La Chapelle patent. These drivers are
?xed in a plate 36 carried by a top-girt-38 upon
side rods 40, 49 reciprocating vertically in the
frame It. The plate 36 is separably mounted in
opposite ways 42 upon the top-girt, it being “
latched by a spring-plunger 44 movable in said
top-girt and received in a depression in the edge
of the plate. The gang of drivers operates in the
corresponding group of multiple die-passages 14,
it ‘being changed together with the quill-plate l8
as the inserting design varies.‘ The side rods 40
areactuated from power mechanism through a
clutch (not shown).
Considering now the features peculiar to this
invention, the mechanism M includes a heel
base-holder m and a top-lift-holder m’ (Figs. 5,
6, 11 and 12). The respective holders have car
rier members 50, 50’, each of which is of L-shape
and has an arm 52 or 52', extending from front to
rear of the machine, from the rear‘ extremity of ;
whichprojects a transverse arm '54 or 54’. The
arms 52 and 52’ of the two holders lie at opposite
sides of the die-‘blockrl2, while the arms 54 and
54' are superposed, thearm 54’ of the holder m’
being uppermost.
They are adjustable fore and ‘ a
aft by virtue of their support upon the heads of
screws 56 or 56’, threaded vertically into the un
derside of the die-block and passing through slots
58'or 58' extending longitudinally of the carrier
arms 52. One of the rear screws 56" at the op
posite ends of the transverse arms 54 and 54’ may
be common to the two‘ carriers, through openings
58" in which they pass. To vary the position of
the holders, the forward extremity of each of ‘the
arms 52 and 52' has a depression 60 or 60’ in
which lies a collar 62 or 62’ upon a screw 64 or
64', threaded horizontally into the front of the
die-block and rotatable by a head 66 or 66'.
With the screws 56 and 56’ loosened, either of the
screws 64 or 64’ may be turned by its head situ
ated conveniently for the operator at the front
of the machine, and the holders m. and m’
brought to the correct relation to each other and
to the passages in the die-block for the particular
inserting design in use. In this adjusted posi
tion,‘the carriers may again be locked by tight

, ‘ intersection of said arms opposite projections 82,
82, while at their forward extremities are rotat
‘ able about vertical axes rolls 84, 84 having re
duced peripheral portions (Fig. 3).
Upon the
arms of the base-holder m (Fig. 6) are similar
ly situated rear contact members 88, 88 and for
ward contact members 90, 90. These are shown
as levers fulcrumed at92 beneath the arms and
each urged normally down at its inner end by an
expansion-spring 94 interposed between it and
the arm upon the inner side of the fulcrum. The
contact of the outer end of the lever with the arm
determines its normal ‘angular position. As in
dicated at 96 in dash-lines in Fig. 6, contact-rolls
may be placed upon the inner ends of the levers
96, if this be desirable.
In applying heel-parts to'the holders 1n and m’,
the operator presses a lift T between the rolls
84, the arms 12 of the holder mf yielding against
their spring 18' tov admit the lift and the rotation
of the rolls facilitating the inward movement.
This continues until the rear of the lift at the
opposite sides of the longitudinal axis strikes the
arm-projections 82. These furnish a back-stop
which determines the position of the lift along
this longitudinalaxis. ' As the operator frees the
lift, the pressure of the rolls against the opposite
sides betweenthe breast and the center will turn
said lift about a vertical axis, if it is not already
symmetrically located, until the longitudinal axis
. is centralized with'respect to the passages I4 in
the die-block I 2 and its quills 24. In this rotation
of lift,‘ it remains in engagement with the pro
jections 82, so its position from front to rear of
the die-block is determined. A heel-base H is
similarly inserted between the arms of the holder
m against the levers 88, the unfinished periphery
projecting beneath the reduced peripheries of the
rolls 84 and is turned by the contact of the inner
ends of the levers 90 or the rolls 96 upon them, its
correct location both longitudinally and angular
ly ‘being attained in the same manner as the
lift T.
Were it necesary to insert the lifts into the
holder m’ in contact with the ends of the spaced
quills 24, there would tend to be interference with
